One-line Definition
IML labels designed for food packaging applications, integrated directly into injection molded containers for durability, hygiene, and premium shelf appearance.
What It Is
In-Mold Labels (IML) specifically developed for food packaging, applied during the injection molding process to become an integral part of the container rather than a surface-applied label.
Why It Matters
Food packaging requires stable labeling performance under conditions such as cold storage, moisture exposure, oil contact, and repeated handling.
IML provides consistent appearance, strong adhesion, and reduced contamination risk compared to post-mold labeling.
Material Type
- Polypropylene (PP) based films
- Food-contact compliant substrates (according to applicable regulations)

FAQ
FAQ Q1
Is IML suitable for frozen or refrigerated food packaging?
FAQ A1
Yes. IML labels are commonly used in frozen and refrigerated food packaging due to their strong adhesion and resistance to moisture and low temperatures.
FAQ Q2
Can IML replace traditional adhesive labels for food containers?
FAQ A2
In many food applications, IML can effectively replace adhesive labels by offering better durability, cleaner appearance, and improved production efficiency.
